存在层间水和凝析水的裂缝型气藏物质平衡方程

摘要

针对存在层间水和凝析水的裂缝型气藏,常规物质平衡方程计算出的储量不够准确。为解决这一问题建立考虑层间水和凝析水的裂缝型气藏物质平衡方程,同时针对不考虑形变、不考虑形变和凝析水、不考虑形变和产水这三种情况,对新建立的物质平衡方程进行简化。实例研究表明,应用新建立的物质平衡方程能够满足生产的需要。%In response to the fractured gas reservoirs with interlayer water and condensation water,the calculated gas reserves are not accurate by using normal material balance equation.To settle this matter,this paper builds a material balance equation of fractured gas reservoirs with interlayer water and condensation water,and simplifies this equation in three types which are ignoring deformation,ignoring deformation and condensation water and ignoring deformation and water.Studying the application of the new equation,the case study illustrates that this new material balance equation can meet the production requirements.
